Ultrasound at 5 weeks 6 days?

Ellie

I am having a scan on Saturday when I will be 5 weeks 6 days pregnant. I had a scan at 4 weeks 1 day (didn't know at the time how early I was due to irregular periods) but obviously they couldn't see anything that early. What are the chances they will see something on Saturday? Will they see a heartbeat? So excited and nervous!
